PAR QUET FLOORING.

To all lwhom imag concern:

Be it known that I, SALAMON Unsinn, a citizen of the United States, and resident of the city of New York, in the county of New York and State olvNew York, have invented certain new and `use'liul lmprm'euients in Parquet Floorings, of which the following is a siiecitication.

rlhe present invention relates to improvements in wooden floorings, and more particularly to that type which is termed parquet flooring.

.lf a parquet flooring is tobe laid upon a cement, stone, or similar substratmn, first a foundation floor, that is to say an ordinary wooden floor, must beilaid on top of such substratum, and upon this ordinary floor are then laid the wooden tesserze or blocks, the parquet flooring so formed being attached to the foundation floor in the well known manner. Such work comprises two distinct and separate operations, that is to say the construction of the foundation floor ln laying the parquet iiooring, each wooden tessera must be separately attached to the foundation floor andinterlocked with those adjoining it. a

One of the objects of the present invention is to construct a parquet `flooring for use upon a cement, stone or similar si'ibstratlun, which does away entirely with the foundation floorii'ig, or rather combines the foundation flooring and tlu` parquet flooring in one integral structure.

Another object of the inventiouis to provide a parquet door construction of the chai'- aeter specified, which is comparatively inexpensive, and the laying of which can be effected in a comparatively short time with little labor, and still is both in appearance and durability equal t0 those heretofore in use.

llfith these and other objects in view, which `will more fully appear as the nature of the invention is better understood, the saine consists in the combination, arrange ment andconstruetion of parts hereinafter fully described, pointed out in the appended claims and illustrated in the accompanying drawings, it being `understood that many changes may be made inthe size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the Specieatonof Lcttersilateiit.

spirit o r sacrificing any of the advantages of the invention.

panying drawings, in which Figure 1 is a plan view of a parquet flooring constructed in accordance with the present invention; Fig. 2 is a section taken on line 2-2 of Fig. 1; Fig. 3 is a section taken on line 3-3 of Fig.` 1; Fig. 4 is a plan view of an element of the flooring; and Fig. 5 is a section taken on line 5-5 of Iiiget.

In the drawings, the numeral 10 indicates the cement or stone substratum, in which are formed, preferably, equidistantly holes 11, 11, into which `are driven wooden plugs or wedges 12,12. Upon the cement are placed at proper distances furring strips 13, 13, to provide an air space between the cement and the parquet flooring. These strips may be held in position upon the cement by any suitable means.

The parquet flooring comprises flooring boards 14, 14, which correspond in length to the width of the room whichis to be provided with a parquet flooring'. Each of these boards is composed of two longitudinal strips 15, 15, having grooves 16, 1G in their inner faces, said grooves micommodatingthe tongues 17, 17 of transverse blocks 1S, 18. The blocks 18, 1S are `interconnected by grooves 19 and tongues 20. The object of making these boards of longitudinal strips and transverse blocks is toprovide a struc ture which is not warped or distorted by heat or moisture. The upper faces of the .strips 15 are provided with longitudinal grooves 21, 21, which extend throughout the length of the said strips and accommodate locking strips 22. which are T-shaped in cross section, and adapted to be fastened to the wooden plugs or wedges 12. The upper surfaces of the flooring boards are covered by a layer of tcsserai, that is to say small wooden pieces or blocks 23,` 23, said tesserie being cemented to the iiooring boards 14 and to each other by a wood cement, or are fastened thereto and to each other by any other suitable means. The wooden blocks or pieces 23 may have any regular geometric form to produce an artistic desien.

In layingthe flooring, first the desired number of holes 11 is drilled at suitable intervals in the substratum 10. Into these holes are then driven the Wooden plugs 0r Wedges 12, after which the furring strips 13 are put upon the substratum. rlhe flooring boards lil are then cut to the proper lengths, and placed side by side upon the furring strips throughout the Width of the room in parallel relation to each other at suitable distances, to provide proper spaces for the locking strips 22. lt is to be observed that the Wooden pieces or blocks 23 are secured to the flooring boards before the latter are cut to the proper length. The T-shaped strips are then engaged With the longitudinal grooves 21, 21 in the iooring boards and securely fastened to the cement substratum by means of screws 24, or other fastening devices, which are driven through the said strips into the plugs or Wedges 12. After this operation Wooden pieces or strips 25 are attached by suitable cementing means, or otherwise, to the upper faces of the locking strips 22, thereby concealing the fastening means 2li. rl`he outer faces of the pieces or strips 25 are arranged flush with those of the Wooden pieces or blocks 23, whereby a parquet floor is obtained which is in ape pear-ance identical with those heretofore in use. rlhe design of the Wooden pieces or strips 23 and 2e may be varied, and the said pieces or strips may be either of the saine color or of different colors to suit the requirements.

Fre-m the foregoing it will Ibe observed that, in constructing this parquet flooring, the foundation flooring, which is to be placed upon a cement or stone substratum, is entirely done avfay with, or rather' the foundation flooring and the parquet flooring are ctnnbined int-o one integral structure. lt will be observed furthermore that due to tais combinatie-n, much material is saved, and, inasmuch. as the wooden blocks or pieces 23 are previously attached to the flooring' boards 14, the flooring can be laid in a comparatively short time with little labor, and involving small expense. Moreover, since the tesserae 28 are not interloclred, the cost of the structure is still further reduced.

1What l claim is 1. rbe combination with a cement substratum, of furring strips placed thereon, flooring boards provided with longitudinal grooves in their upper faces placed side by side upon said vfui-ring strips in parallel relation and close to each other, the upper faces of said flooring boards being covered by Wooden tesserae, locking strips T-shaped in cross section attached to said cement substratuni and fitting the grooves in said flooring boards, and Wooden strips secured to the upper faces of said locking strips, the outer surfaces of. said Wooden strips being flush With those of said tesserze.

2. The combination With a cement substraturn having holes therein, of plugs driven into said holes, furring strips placed upon said substratuni, flooring boards provided with longitudinal lgrooves in their upper faces placed side by side upon said furring strips in parallel relation and close to each other, the upper faces of said flooring boards being covered by Wooden tesser, locking strips T-shaped in cross section fitting the grooves in said flooring boards, fastening devices driven through said locking strips into said plugs, and wooden strips secured to the upper faces of said locking strips covering said fastening devices, the outer surfaces of said Wooden strips being flush With those of said tesserse.

3. The combination` With a cement substratuin, of furring strips placed thereon, flooring boards provided With longitudinal grooves in their upper faces placed side by side upon said furring strips in parallel relation and close to each other, each iiooring` board being composed of tvvo longitudinally rabbeted strips and of a plurality of transverse blocks lhaving' tongues in engagement With said rabbets, the upper faces of said flooring boards being covered by Wooden tesserae, locking strips T-shaped in cross section attached to said cement substratum and fitting thel grooves in said flooring boards, and Wooden strips secured to the upper faces of said locking strips, the outer surfaces of said Wooden strips being flush with those of said tesseree.
